Massimo Ferrario (LNF)29/09/2016, 16:50The SPARC_LAB test facility hosts a 150 MeV high brightness electron beam injector, which drives a FEL source, a THz radiation user beam line and an X-ray Thomson backscattering experiment. A particle driven plasma acceleration (PWFA) experiment is also under way. In parallel to that a 200 TW laser is linked to the linac and is devoted to explore laser-matter interaction, in particular with...Go to contribution page

Cristina Vaccarezza (LNF)29/09/2016, 17:20The SPARC_LAB Thomson source is a compact X-ray source based on the Thomson backscattering process. The electron beam energy ranges between 30 and 150 MeV, the electrons collide head-on with the Ti:Sapphire FLAME laser pulse the energy of which ranges between 1 and 5 J with pulse lengths in the 25 fs–10 ps range, providing an X-ray energy tunability in the range of 20–500 keV. After the second...Go to contribution page

Tohru Takahashi (Hiroshima University)29/09/2016, 17:35Oral presentationThe power enhancement by an optical resonant cavity is a novel method to achieve intense laser pulses for laser Compton scattering, however, it requires high precision control of the optical path to keep it on the resonance. We have beeｎ developing a new scheme to avoid this difficulty using a feedback free optical cavity with self-reconating scheme. In this talk, we report the status of...Go to contribution page

Illya Drebot (M)29/09/2016, 17:50We present the design of a photon-photon collider based on Compton gamma sources for the observation of elastic γγ scattering. Two symmetric relativistic electron beams produce two primary gamma rays through Compton back scattering with two high energy lasers. The elastic photon-photon scattering is analysed by start-to-end simulations from the photocathodes to the detector. A new Monte...Go to contribution page

Vladimir Shpakov (LNF)29/09/2016, 18:05The plasma wake-field acceleration (PWFA) is the promising type of acceleration, that recently had shown not only ability to produce a high energy beams at short distance, but also increasing quality of the beam in terms of energy spread, emittance and stability. Increasing quality of the PWFA beams opes for us an opportunity to create a compact FEL type sources of radiation. In this work we...Go to contribution page

Alessandro Curcio (LNF)29/09/2016, 18:20The betatron radiation from electrons accelerated in laser-produced plasma channels typically extends in the X-ray region, with a broad synchrotron-like incoherent spectrum. Nevertheless the radiation spectrum and the degree of coherence of the betatron radiation can be efficiently modified according to different laser-plasma interaction schemes. The betatron radiation seems to be a good...Go to contribution page
